 * Portale clienti Quantirica - foglio di stile unico (C-06, WORKPLAN §3-bis).
 * Sopra Bootstrap 5.3. Principi: font di sistema, un colore di accento, contrasto AA,
 * niente gradienti/trasparenze, stato sempre scritto (il colore e' solo un rinforzo).
 * I nomi delle classi storiche (.modern-card, .btn-primary-modern, ...) restano validi
 * perche' le pagine non ancora riscritte (C-07..C-09) li usano.
